It seems someone worked out that the Realtek RTL2832U found in various very cheap USB DVB-T decoders can be repurposed as a complete software-defined radio. The sidebar of this subreddit seems to be the best place to start.

I found it more productive just go to Osmocom’s site and Gnuradio’s site directly. The compendum of personal sites was basically useless. And Reddit was even worse than useless: misleading and just makes people wasting time while trying to distinguish information from disinformation.http://sdr.osmocom.org/trac/wiki/rtl-sdrhttp://gnuradio.org/

Basic things like FM radio work fine, but getting UAT weather turned out to be challenging: the bandwidth is too great for the sample rate that RTL chipset can deliver. Still tinkering with it, but about ready to buy a real SDR.
